Could you please file bugs for the issues you found? It's the only way there is the chance to get this fixed. It is the only way to guarantee the attention of the relevant developer. Thank you.

Subject: [Interest] Custom SQLite and linking woes
Message-ID:
Hi list,
I've run into a bit of a problem with the way, that I'd like to use SQLite
in my application.
I need to load an extension, which is turned off by default in Qt, so I've
made the following change to `qtbase/src/plugins/sqldrivers/sqlite/
sqlite.pro`:
DEFINES -= SQLITE_OMIT_LOAD_EXTENSION
DEFINES += SQLITE_ENABLE_LOAD_EXTENSION
And then recompiled and installed the plugin as advised in
http://doc.qt.io/qt-5/sql-driver.html:
I'm on macOS, so I've been building against the Homebrew version of of
sqlite3 like so:
$ ~/Code/Qt/5.9/clang_64/bin/qmake
"INCLUDEPATH+=/usr/local/Cellar/sqlite/3.21.0/include"
"LIBS+=-L/usr/local/Cellar/sqlite/3.21.0/lib -lsqlite3" sqlite.pro
I `make install` and then try to use the new plugin and then this error
appears:
dyld: Symbol not found: _sqlite3_intarray_bind
Referenced from:
/System/Library/Frameworks/CoreData.framework/Versions/A/CoreData
Expected in: /usr/local/Cellar/sqlite/3.21.0/lib/libsqlite3.0.dylib
in /System/Library/Frameworks/CoreData.framework/Versions/A/CoreData
The program has unexpectedly finished.
Apparently *CoreData* expects *_sqlite3_intarray_bind* to be defined, but
clearly this isn't present. There's a slight difference in the symbols
available from the systems installed version of sqlite3 and the Homebrew
supplied one:
$ diff _sqlite3_bind_pointer
18d18
< _sqlite3_intarray_bind
So, from what I've been able to gather searching for answers regarding
*_sqlite3_intarray_bind,* the solution is to just unset *DYLD_LIBRARY_PATH*,
but ... that sort of defeats the purpose of trying to use a custom version
of sqlite. E.g this answer: https://discussions.apple.com/thread/6646506.
Now, unticking the "Add build library search path to DYLD....." in the run
settings, does enable the application to properly load and run but.. again,
with the wrong version of sqlite:
SELECT sqlite_version(); # returns "3.16.1"
As far as I can tell, this is the version that ships with Qt 5.9:
$ grep "3\.16\.1" ~/Code/Qt/5.9/Src/qtbase/src/3rdparty/sqlite/sqlite3.h
#define SQLITE_VERSION "3.16.1"
So, what to do here...?
The weird thing is, that if I run these queries in with that version;
3.16.1:
select sqlite_compileoption_used('ENABLE_LOAD_EXTENSION');
select sqlite_compileoption_used('OMIT_LOAD_EXTENSION');
I get back the results of *1* and *0*, which would indicate that he
recompiled plugin somehow picked up the compile time change. Trying to run
a `select load_extension(..)` query however throws back the `not authorized
Unable to fetch row` error indicating extension loading is still not
enabled. And in case you're wondering, I am running
`sqlite3_enable_load_extension(db_handle, 1)` before any of this.
I've tested the 3.21.0 binary of sqlite via the command line and it can
execute a `select load_extension(...)`, query just fine.
Any pointers with this, is much appreciated.
Best regards,
René Hansen

Subject: [Interest] Qt 5.10, iOS and 32 bit iOS devices
Message-ID:
Hi,
I have recently updated on of my apps to Qt 5.10 and I have also built it against iOS 11 SDK.
I started having users complaining about not being able to run the app on 32 bit iOS devices.
I thought the problem was compiling it with iOS 11.
I have submitted another version where the binary was built against iOS 10. The problem is still happening, so now the only variable left is Qt 5.10
Does anyone knows what is happening? I’m a bit in the dark here.
Thanks!
Regards,
Nuno

Jake,
Thanks for your feedback.
I was just trying to old the train for a few of my loyal customers. I praise more for them then Apple for theirs! ;)
But that’s fine with me. I won’t go back below Qt 5.10 now.
Thanks once again for your prompt reply!
Best,
Nuno

the QtCipherSqlitePlugin seems to be targeted also for fruit OSs. Works

Subject: [Interest] Trouble with include path building qtwebkit on ubuntu
Message-ID: <9b41279e-b8b3-c99e-b940-264ce4be9415@schultz.la>
Hello,
As a complete Qt newbie I'm trying to make a static build of Qt5 and
QtWebkit for the purposes of making a static build of an application
that uses them.
I'm using tarballs qtwebkit-opensource-src-5.9.0.tar.xz and
qtwebkit-opensource-src-5.9.0.tar.xz on a system with no qt packages
installed (just to make sure I'm not polluting my custom build with
system versions).
Qt built without problems. But when I came to build qtwebkit it seemed
to use hard-coded locations /usr/lib/x86_64-linux-gnu/qt5/include and
/usr/lib/x86_64-linux-gnu/qt5/include/QtCore/ for its include path.
Poking around a little I could see that these values were defined in
Makefile.WTF and Makefile.LLIntOffsetsExtractor but couldn't see any way
to override these values so that I can build qtwebkit without having to
install Qt5 system-wide.
Can anyone offer a pointer on how I might achieve this?
Thanks as always,
Jonathan

Seems like you have (at least parts of) Qt installed system-wide, and you
used system-wide qmake for building. You need to use qmake from your Qt
build, so system-wide Qt installation won't be used.
Also, you should not use qtwebkit-opensource-src-5.9.0.tar.xz for anything.
Use 5.212 branch instead [1]. If you absolutely have to stay with 5.9 branch,
use git branch, not 5.9.0 tarball
[1] http://code.qt.io/cgit/qt/qtwebkit.git/
Latest tarball can be found at
http://download.qt.io/snapshots/ci/qtwebkit/5.212/latest/src/submodules/

Subject: [Interest] Video acceleration with gstreamer 1.0 omx and Qt
5.9.4 / 5.10 eglfs on RPI3 (brcm)

Message-ID:
Well, so couple days more of testing Yocto and Boot2Qt the issue seems to
be in the Qt somewhere.
I decided to build Qt 5.9.4 and even 5.10.1 snapshot using latest Boot2Qt
layer.
Adding gstreamer1.0-omx to the layer and building the image with that
results in a great smooth video when played with gstreamer directly,
ie gst-play-1.0 test.mp4 (this video comes from youtube-dl -f 137+140
https://www.youtube.com/watch?v=T63MCogI4sM)
but playing that same video using Video qml element there are obvious frame
drops.
In essence there is no ability to get a smooth video playback on RPI3 by
using Qt/QML and any stock method approach as of this moment using bcm or
vc4 driver with buildroot, yocto, rasbpian or archarm.
This definitely surprised me as default Boot2Qt image is obviously unusable
for the RPI QML Video playout. I ran out of free time, so I doubt I will
have time to investigate more.
Next I would try latest gstreamer in hope that there were some improvements
in the sink element that QML uses since 1.10.4 is built by Boot2Qt and
1.12.4 is the latest if I am not mistaken.
Best regards,
Petar

What excatly are you trying to achieve? That the position of the sphere
is updated when data is incoming as the QVector3D?
Then you simply have to set the translation on the sphereTransform to
the vector and the scene will be updated.

Be careful with the names ;) You are thinking of QtWebKit and QtWebEngine. Qt
also has a module called QtWebview which wraps native webviews on iOS and
Android and WebEngine on other platforms.

Are you sure you can't specify any orientation with these angular ranges?
Are you looking at all the three rotation angles in the example you gave in
your bug report (i.e., the 'roll' angle might be 180 for your cases when
you are expecting the pitch angles to be greater than 90)? Android
orientation has one angle that only has a range of 180 (-90 to 90) degrees
too (same as QRotationReading
).:

Hi Dimitrios,
You don't need to change or add repositories to update Qt. However,
the update process depends on how you installed Qt in the first place.
If you used the Offline installer, then you cannot use the Maintenance
Tool to update Qt. You must download the new installer for Qt 5.10.
If you used the Online installer:
1. If you also used the Qt SDK Repo Chooser
(https://github.com/JKSH/QtSdkRepoChooser), then you must re-run the
Chooser tool first. If you didn't use the Chooser tool before, ignore
this step.
2. Run the Maintenance Tool and select "Update components". You might
need to run this more than once, until there are no more updates.
3. Finally, select "Add or remove components". Here, you can add Qt
5.10 to your system.
Regards,
Sze-Howe

Subject: [Interest] restoreOverrideCursor not working in 5.10
Message-ID:
I'm seeing restoreOverrideCursor() not working in Qt widget applications
built with Qt 5.10 under Windows 7. The normal cursor only returns when it
moves off the app, or at least off the widget it was over when the
hourglass was turned on. 32-bit MinGW and 64-bit MSVC2017 both do this. I
also see it happening in Qt Creator 4.5.0 (not built by me). I do not see
this with older versions of Qt.

Subject: [Interest] QFileDialog not localizing in Qt 5.4.2
Message-ID: <15946722-74a9-b2d7-f38d-d15feff89b30@comcast.net>
I have a customer who is trying to localize a stand-alone Qt application for
the Japanese market. Everything seems to be working except for QFileDialog.
It is still displaying with English text, while the rest of the application
shows Kanji. He is actually /in/ Japan, so any display of English on his
machine is an unlocalized anomaly.
The main.cpp of the application consists of the following:
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
// Qt translations
QTranslator qtTranslator;
qtTranslator.load("qt_" + QLocale::system().name(),
QLibraryInfo::location(QLibraryInfo::TranslationsPath));
a.installTranslator(&qtTranslator);
// Application translations
QTranslator nrcTranslator;
nrcTranslator.load("controller_" + QLocale::system().name(),
QLibraryInfo::location(QLibraryInfo::TranslationsPath));
a.installTranslator(&nrcTranslator);
MainWindow w;
w.show();
return a.exec();
}
The (pretty standard for Qt) code that is opening the dialog looks like:
QString path =
QDir::toNativeSeparators(QFileDialog::getExistingDirectory(this, tr("Select
Config Folder"), prefs["config_path"].toString()));
The translations path includes the "qt_ja.qm" file (see the attached screen
shot). I checked the *.qs files in the source distribution, and "QFileDialog"
appears to have its translations contained in the "qtbase_ja.qs" file, so I
provided the compiled version ("qtbase_ja.qm") to them. However, placing that
into the translations folder doesn't appear to have any affect.
Has anybody else had problems with this?Might I be doing something incorrectly?

As Boudewjin points out, it is OS X. The customer points out that the Windows
version works correctly.

Hi Bob,
looks like QTBUG-65001 which should be fixed for 5.10.1.

Thanks. That bug report lists multiple monitors as a possible cause. I
have 2 monitors, and I just tried disabling one. The problem went away in
a test app, and came back when I re-enabled the 2nd display.

Since they are a major reseller of our product in the Japanese market, and are
located in Tokyo, I would feel comfortable answering yes to that question.

Then I don't know the actual answer, but would venture that you need some
specific key in your bundle's Info.plist to trigger the Apple API to translate
itself.

Hi,
I’m having an awkward problem when using the Maintenance Tool from Qt with a fresh install of 10.13.2 High Sierra Mac OS X with Xcode 9.2 installed.
The application fails with a error that has no workaround. It says: You need to install Xcode version 5.0.0.
Does anyone had the same problem recently?
Thanks!

It seems this was caused by having installed xcode command line tools via brew. Running the following command fixed the issue:
sudo /usr/bin/xcode-select -switch /Applications/Xcode.app/Contents/Developer

Subject: [Interest] Understanding issues with Qt3D shadowmap example
Message-ID: <0a776499-861e-8cad-25d4-014ecfefd470@ifm-chemnitz.de>
Hi,
I'm currently playing with the shadowmap example of Qt3D. When having a
PlaneMesh at (0, -5, 0), a CuboidMesh (width=height=depth=1) above the
PlaneMesh at (0, -4, 0), and a directional light source at (0, 30, 0) no
shadow is visible on the plane. Because the CuboidMesh is above the
plane I would expect a shadow to be cast on the PlaneMesh. Adding a
small change in position of the light say (0.001, 30, 0) procduces a
shadow on the PlaneMesh.
Do I miss something important?
Cheers Volker

Immediately after sending the question to the list, I solved my problem
by providing a correct upVector to the lightCamera. Previously upVector
and light direction were collinear :(

Immediately after sending the question to the list, I solved my problem
by providing a correct upVector to the lightCamera. Previously upVector
and light direction were collinear :(

Subject: [Interest] iOS libpng conflicts with another lib
Message-ID: <3802de9631f0e3ae8c0ab3c0fa4ca17b@virtual-winds.org>
Hello,
I have an external lib build statically into my qt app (5.9.4,
widget-based). That lib can optionally support internally png images. If
I activate this, there is no problems in other platforms (I tested
Android, Windows, Linux, Raspberry, MacOS), but on iOS as soon as I try
to open a png image with a QPixmap or a QImage it crashes. If I compile
my external lib without png support no more crash.
So it appears that libpng from Qt and the one from my lib are
conflicting, but only on iOS.
Any idea why this occurs on iOS and what I could do to avoid the crash?
I badly need png support in both qt and the external lib.
Thanks
Philippe

Are there any clues you can get from XCode debugger of from crash-report of iOS
like where it happens and what is corrupted?
Kind regards,

Build both Qt and that library against same libpng

Preferably a system-wide one, if such a thing exists on iOS.
